1. Thomas E. Phipps, Jr., The Marinov motor: A skeleton in the closet of physics

The Marinov motor (MM) is a device whose operation has been verified by several independent investigators. This fact is an embarrassment to physicists, since their accepted Lorentz force law is unable to account for it. Full understanding of the MM seems to require (1) a more robust interpretation of the relativity principle, (2) recognition that first-order physics has never been right (in view of the Galilean noninvariance of Maxwell’s equations), (3) acceptance of force action by vector potential A, and (4) willingness to abandon covariance in favor of invariance.
